to simplify the equation just subtract 9-7 which simplifies to 11x+2

If you're just simplifying the expression and not solving, it would equal 11x + 2. You just have to combine like terms, so 9 - 7 and then add the 11x onto it.

How do you find the area of a triangle and please show examples

Answers

to find the area of a triangle, u multiply its base and height, then divide by 2.

the formula for area of a triangle is:
A= B(base)h(height)/2

There are several ways to find the area of a polygon, but because you're in middle school, you'll most likely use; A = 1/2b * h; where A = area, b = base, and h= height.

Say you have a triangle, the bottom of it is 4 meters and it is 6 meters tall this is not the same thing as a side length. You would divide 4 by 2, which is the same thing as as multiplying by 1/2, and multiply it by 6.

So A = 1/2*2*6
A = 1 * 6
A = 6
